Overview

Selective Hue/Saturation is an effect block that adjusts the hue and saturation of a specific color. It can be used as a standalone effect or in tandem with a Chroma Key block to remove color spills that may remain on your subject layer.

Controls

Chroma Selection

The first color input field determines the color to control saturation of. You can use the eyedropper tool featured on the block to select a color from the layer itself, or if you have a specific color, you can enter a HEX value in the input field.

Threshold

Similar to Chroma Key, threshold controls the similarity threshold for pixels that will be affected. A value of 0 means only exact color matches will have their saturation adjusted.

Smoothing

Smoothing softens the edge of the pixel selection that will be desaturated. Higher smoothing values mean more pixels will be affected. A value of 0 means no smoothing is applied.

Hue

Adjusting the hue shifts all the colors in the image around the color wheel. For example, changing the hue value by 180 degrees will turn red into cyan, green into magenta, and blue into yellow.

Invert

With invert activated, all pixels besides the selected chroma will be desaturated. Pixels that match the selected chroma will not be affected.
